Purpose

This blog aims to provide information about the effect of mental illness and its prevalence globally. The blog address questions about country, continent, age, and gender, and how each of these factors can play in to the proportion of people suffering with mental illness. The goal is to show which groups of people, specifically by country, age, and gender, are at the highest risk of mental illness to find which groups need the most support from those who are able to help. The data used within this blog is from the Our World in Data website from the Global Burden of Disease and includes mental health information from 1990 to 2019.

Covid-19 Disclaimer

Since 2020, Covid-19 has taken over the lives of people everywhere. From quarantining in homes and having no social contact, to constant testing, the mask frenzy, and difficulties adjusting to this “new life,” it is no surprise that Covid-19 has affected the mental health of the entire global population. The prevalence of depression alone has increased 7% after the outbreak (Torales 2020). Because the data used ranges from 1990-2019, the largest limitation in our data is that Covid-19 is not factored in the datasets and therefore the numbers used below might not be accurate to today’s date.

Global Prevalence of Depression

Map

We show the global prevalence of depression from 1990 to 2019 in the map below. Through this visual, we can see that the percentage of people diagnosed with depression has increased over the years.

Global Prevalence of Depression by Sex

We have also decided to take a closer look the global prevalence of depression from 1990 to 2019 by sex in the map below. Through this visual, more females are diagnosed with depression compared to males over the years. We also see that there is an increase of prevalence across both groups over the years.

Relevant Countries

We decided to take a closer look at the increase of mental illness prevalence in China, the U.S., India, Pakistan, and Brazil. India had the overall highest increase in mental illness prevalence, and the other countries followed in their respective order. The numbers shown are the number of people who have reportedly been diagnosed with a mental illness, in millions.

Summary

Throughout this blog, we have found that mental illness has greatly increased throughout the years, with females having a significantly higher prevalence than males. Brazil, China, Pakistan, India, and the United States have the highest proportion of citizens with mental illnesses, to which can be attributed to the many wars and traumatic event that have taken place within those countries in the last 20 years.

We found that globally, those in the older age bracket (50+) are more likely to suffer from mental illness, yet in the United States, the most at risk age group is 15-49 year olds.

2022 data vs. 2019

In the first year of the COVID-19 pandemic, global prevalence of anxiety and depression increased by 25%, according to the World Health Organization. Young people, mostly college aged students, and women were impacted the most. Therefore, since the Covid-19 pandemic hit the world, mental illness prevalence has drastically increased and there are not enough resources available to help all those in need. We hope that through our blog, we were able to raise awareness, and below you can find mental health resources if you or someone you know is struggling.
